I recall, when I was a kid, having to read a book and then write a book report. Which I hated doing.
With the benefit of hindsight (a lot of it), I now see the value - it ups your vocabulary/grammar to have to read it, as well as write it.
Did I understand every word? Nope - not close - but enough that I was following the plot pretty closely. Then I wrote the attached. Comments welcome, I didn’t post the whole thing here as it’s 1+ pages (A4 size)
Now, I’m going to go back and look closely word for word, phrase by phrase at the construction to help boost vocab/grammar.
